Shear flow in a thin-walled section is defined as

  • A.The shear stress multiplied by the wall thickness
  • B.The shear stress divided by the wall thickness
  • C.The shear force divided by the enclosed area
  • D.The shear force multiplied by the wall thickness

Answer: A

Shear flow is a force per unit length along the wall. It is the natural variable for thin-walled work because it stays constant along a wall of varying thickness, whereas the stress does not, so equilibrium arguments become much simpler.
